Be it known that I, JAMES H. MURRILL, of Baltimore, in the county of Baltimore, and in the State of Maryland, have invented new and useful Improvementsin Machines for Cutting Bunge; and do hereby declare that the following is a. full, clear, and exact description thereof, reference being had tol the' accompanying draw. ings, and to the letters of reference marked thereon. In the annexed drawings making part of this specification A represents a metallic frame ortable, which is supported upon the legs A.v `Upon the upper side of this table, at its front end, is secured a plate, C', which has cast upon-its upper side a standard, and upon the upper end of this standard is c ast acylindrical collar, B., 'Inserted in thehorizontal cylindrical'opening in this collar is a cylinder, C, which has alsquare hole made through it longitudinally.

On one en d of the cylinder C is secured a gear-wheel, B', which gears into a wheel, J, on shaft I. The shaft I lies parallel with frame-A, but'ahove it, being supported und having its hearings in' the uprights ZZ, which are secured to--the side of the frame.. This shaft I is provided with the graduated pulleys J', andthe gearn'heels J and I.

D represents a plate which is secured upon the frame A, and which has its two ends D D turned up,.so that they will support and supply bearings for a hollow cylinder, E, and a horizontal shaft, V. Upon cylinder E, near oneA end, is secured a. geur-wheel, F,.which meshes into the wheel I, and by which is is driven. The cylinder E is surrounded by a collar, E', which is grooved upon its periphery, and which is fitted so that it will t slide upon the cylinder. This cylinderfis' provided withl three long slots made longitudinally of it, yand equidistant apart. G G represent feeders, which consist of metallic straps o r strips, with teeth made in one end, while their other ends are secured fast to the collar E. These feeders have their toothed ends to pass through the long slots in the cylinder. Lying close to plate D is guide-rod Gr', which has secured to it two arms H', which take ih'to the groove in collar E', and also a rackbar, H. This guide-bar moves endwise, and by means of it the collar E is caused to. slide upon the cylinder E, moving with it the feeders G.

X represents a vertical shaft, which yis hel'd in'hearings secured yto the side of the frame A. This shaft is provided with a. crank-handle, and with a gearlwheel, az', which gears into the raclrbarH, and is surrounded with avcoiled wire' spring, d. Qne end of this spring is secured to a clutch-collar,p, while the other end is secured to the shaft'X, and 'thus serves to revolve the shaft in one direction, while its crank-handle serves to revolve it in the other.

Upon one end of the cylinder E is secured a wheel, K, which is formed' so that it will not obscure the opening through. the cylinder.' This wheel has init's face three equidistant grooves, in which are .placed the slides a a a, the inner ends of which arc toothed, `and p rojectrinto the hole in the wheel, which corresponds with that of thc cylinder. These slides are 'regulated hy the setscrews eye and the springsv z' z, sothat they will yield endwise to accommodate themselves -to the size ofthe wood whielris passing through the cylinder.

'The shaft V, which has-previously being adverted to, is provided with a pulley, V". and at one end 'with a head; W, to which is secured a series of cutters,

Upon the frame A, at its-rear end, is placed a sliding frame or carriage, L, which has erected upon it supports L L', in which4 theihorizontal shafts M and T have their bearings. Shaft Mhas secured to it a circular saw, N, and a pulley, P, while the-shaft has secured to it a pulley, S, and the cutters T and (It.l

The carriage L slides in dove-tailed *grooves*l crosswise of the frame A, and is caused to slide backwards and forwards by a. screw, O, which is provided with a crank-handle, O. l

At theyrear end of the frame A is erected a standard, Z, which has secured or forxn'ed .upon its upper end a. sleeve, Q, and through this sleeve passesga rod,-Q, which is pointed, so as to act as acentre at its forward e'nd. Surrcuhding the rod Q,at the rear'end of sleeve Q, is a coiled-wire spring, t, which forces said rod in one direction, while an inclined'plane, from u to 1t on the strap R, forces it in the other. The bar f has a hole in it,

through which the rear end of rod Q passes, and said bar acts against the spring t, while the inclined plane, nt n, Vacts upon it. b is a guide-pin,L which is secured to bar fand it is surrounded with a spring to force it outward after having been forced inward by the inclined plane at n. h represents a set-screw in the upper end of bnrf, which acts upon'the rod Q', when desirable.

v Theoperation of this machine is as follows: When bungs are to be made of lumber not already prepared,I the lumber is first sawed into square stripsof any desired length, so that they may be passed through the square hole in cylinder C. A suitable rest is prepared for the outer end of the strip, to guide it and hold it in proper position. l I

The strip is first fed in by hand until it is caught by the feeders G. The hand of the operator can then be removed, and the feeders G do the work of feeding. Belts pass from a counter-shaft labove the machine to the pulleys on shafts I, V, M, and T, and give them suitable motion. The wheels Iiand J give motion, through wheels F and'B to the cylinders 'C and E, causing them to lrevolve in their bearings. I

It will'thus be seen that the stripbf timber is kept revolving while it is passing through the machine. AS th'e forward end of the strip emerges from cylinder C, the cutters W on shaft V, revolving rapidly, commence Work upon. it, and, cutting its corners off, speedily round it. I The stick pas-ses then into the cylindr E, where it is caught between the feeders G; .The'operatonthem' by tui-ning shaftl X to the right', moves the collar E', and with it the feeders `and rounded stick, causing the' forward ond to pass through wheel K, 'and toward the point of rod Q. When it reaches the'point of this rod, the cutters T on shaft T act upon it and cut it in u ltapering form, such as bungs have, while the cutters u u act upon its edges at its end, rounding it suitably. The operatornow turns the crank-handle O' to the left, causing the plate L to move, and with itthc circular saw N, so that it, the saw, will sever the.bung from `thestick.

The bung being cut in proper shape, the operator turns the crank-handle O to the left, causing thecircular sawto move up and sever the bung from the stick. Before the saw has severed the bung, the point of rod Q is forced back by the springt to follow the inclined plane n n ofthe bar R, thus releasing the'bnng, and allowing it to drop to the floor the instant it is severed, thereby avoiding all danger oi' the saw jamming before it performsits work. The point of the rod Q `moves back simultaneously with the advance movement ofthe saw, and moves up again as the saw rccedes, and is in its proper position to receive the stick for the next bung. l

The operator now, by shaft X, throws back collar E and feeders G, so as to catch a fresh hold on the stick,

the toothed ends of slides La resting against and holding the stick in the mean time..

When the stick is again moved forward, the operation of tapering, bcvolling,.cutting ofi', and 'dropping the.

bung is'the same ashas before been described.

The cutters T are .made long enough to cut the largest, or, rather, longestbungs in use.- T hc set-screw g regulates the size of the bung by setting the plate or carriage L with reference tothe stick asfit is'ses'from wheel K.V l

Having thus fully described my invention, what I claim as new,` and desire to secure by Letters Patent, is-- 1. The arrangement of ,the collar E with its spring-.feeders-G G that lie in the slots of the cylinder E, and are operated to carry the stick through the cylinder after beingV rounded by the cutters, substantially as specified; l f

2. The'wheel .K provided'witht'he slides a a, and placed on the end of the cylinder E for gripng the stick while the bung is being formed, substantially as specified. i

3. The arrangement of the sliding framerL,'wit h shafts T and M 'placed opposite'to each other, one pru- .vided' with the cutters T and u, and the other with the saw N, whereby the bung is formed, cut from the stick,

andl dropped, inthe manner substantiallyas specified.

4. The arrangement ofthe adjustable rod` Q in theV sleeve Q, supported bythe barsf l, and in combination I with the inclined bar R on the end'of frame L., whereby the bung is held and dropped, the whole arranged tooperatev substantially as specied. l

In testimony that Iclaim the foregoing, I have Lhereunto, set my hand, this SthIday of January, 1868.
